yes, Movement of substance down its concentration gradient is a passive transport because it going from high concentration to a low concentration, so it does not require any energy.

Term for the movement of substance against a concentration gradient?
active transport eduction. this is the process in which this moves across. peanut butter jelly time
What is the movement of a substance from an area of high concentration to an area of low concentration?
passive transport Movement down a concentration gradient is known as diffusion.
What is active transport and passive transport?
active transport requires the use of energy aka ATP and is usually against the concentration gradient. passive transport does not require energy because it moves in response to the concentration gradient.
What movement of the substances through a cell membrane against a concentration gradient requires energy?
no because it is a form of passive transport. only active transport requires energy. facilitated diffusion just means that it cant be just absorbed through the membrane, it must go through specific chanels or be helped by transport proteins. but because facilitated diffusion moves from higher to lower concentrations, it requires no energy.
What is the movement of substance from a region of lower concentration to a region higher concentration?
Active transport
Is the movement of a substance to an area of low concentration from an area of high concentration?
passive transport Movement down a concentration gradient is known as diffusion.
What is the movement a substance to an area of low concentration from an area of high concentration?
passive transport Movement down a concentration gradient is known as diffusion.
Is diffusion an active mechanism?
False

What is the movement of a substance against the substances concentration gradient?
Active transport, or reverse osmosis; depending upon conditions.
Movement of a substance down the substance's concentration gradient?
diffusion
What is the movement of a substance from an area of high concentration to an area of low concentration?
passive transport Movement down a concentration gradient is known as diffusion.
What is active transport and passive transport?
active transport requires the use of energy aka ATP and is usually against the concentration gradient. passive transport does not require energy because it moves in response to the concentration gradient.
How does difference in concentration relate to movement of substances across the membrane?
the concentration gradient will help to bring stuff into the cell and to move stuff out. Osmosis likes to move with the concentration gradient. Moving with a concentration gradient is passive transport and moving against it is active transport
What does it means if a substance moves down its concentration gradient?
If a substance moves down its concentration gradient, it means that it is moving from an area where it has a high concentration to an area where it has a low concentration. This is known as diffusion.
What type of molecule movement involves the use of ATP?
Active transport. This is movement of molecules against the concentration gradient.
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
The larger the concentration gradient (bigger difference between the two solutes across semipermeable membrane) the faster the rate of diffusion.
